As Long as Ads Are Still Up = Stock Always Available If there's a 10-minute warranty label, it means your gems will be delivered within 10 minutes at the latest!! How to Trade: Via Mailbox—just provide your username in the Itemku nickname column. REMEMBER!! Username, not display name (correct usernames always have an @, e.g., @FAVMART). Errors in usernames are not our responsibility. Delivery will be processed when the store is operational Hours: 10:00 AM - 12:00 AM If responses are slow, the admin might be occupied with other activities, like showering or eating, so please understand. But we'll do our best to respond quickly. Stock is always updated according to the owner's inventory.
